# Math Lesson - Base 10 and standard Subtraction, Grade 1

• ### Activity 2 / Subtracting with Base Blocks Worksheet

Base ten blocks offer little mathematicians concrete ways to understand how place value works when it comes to subtracting. With this fun and easy-to-follow worksheet, they'll look at the subtraction problems and then use the blocks that are crossed out to help them solve the subtraction problems with accuracy. When they can see equations in representation, they'll be able to work on their automaticity with number reasoning as they come across larger numbers.

• ### Activity 3 / Which Is Correct? Math Worksheet

Young mathematicians will be able to gain mathematical confidence as they use this bright and colorful worksheet to solve subtraction problems. They'll be able to use the base ten blocks representations to subtract, and then they'll look for the appropriate number sentence to match the representation of the blocks. It's great practice for developing number sense that will lead to automaticity for higher-level math problems.

• ### Activity 4 / Subtraction Quest Worksheet

Let your little mathematicians take a math quest full of fun! This free and downloadable PDF worksheet will have them use base ten block representations to decide whether the difference for each problem is 34. They'll solve each problem in the quest, and then mark the equations where the difference is 34, building number sense and challenging themselves at the same time! They won't even know it's math because it'll be so much fun!

So engaging
We love how we can focus on math with this app. It is engaging and we love how we are able to adjust and tailor the levels according to our son’s knowledge and skill levels!

Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.
